Gently nudge you on one thing though - magnetic capes actually use neodymium magnets which have way more grip than the old snaps, you just gotta get the positioning right on the neckline.

Crazy how little changes like that end up being the thing everyone notices.

@benwilliams nailed it, the math never accounts for how fast you'll crack.

Yeah, I actually read something a while back about how light color temperature matters way more than people think for reading. The guy was saying that warm white shades around 2700K are better for winding down but if you actually need to focus, something closer to 4000K or 5000K works better. Swapping to a white shade does the same kind of thing, it just lets more of the actual bulb light through instead of filtering it brown. You're basically getting the full brightness you paid for.

Read somewhere that backwards tires actually channel water to the center instead of out.
